CIY Mix (Middle School) Dates: June 17th through June 20th Location: Cedarville University Spots Available: 16 Cost: $480 due March 31st ($130 due for registration) MIX is a 4-day summer event built for middle school brains, hearts, and bodies. That’s why the Gospel is taught in a way they understand. It’s why small group discussions aren’t an afterthought. And it’s why we play a lot. Moments at MIX change lives and could be the most important four days of your youth ministry calendar.
